`URIBone` needed

[phorward]

Similar to #1155, why isn't there an URIBone to specify valid URLs and URIs?

The requirements must be evaluated, here are some ideas:

• Accepted protocol (http, https...)
• Accept, or accepted ports?
• Local path, may start or not start with /
• Clean-up
  • accept or deny GET-parameters
  • domains disallow list

Relates to #1218, I already missed such a bone for several use-cases in the past.
